"There are many resources available to help citizens register and vote in these important contests," said Carol Aichele, secretary of the Pennsylvania Department of State, which handles voter registration. "Voters can visit http://www.VotesPA.com to check their registration status, download a voter registration form and find information on their polling place."

Applications from Pennsylvanians registering for the first time, changing their address or changing their party affiliation must be postmarked or delivered to the applicant's county board of elections by the close of business Monday.

Aside from being 18 or older, would-be voters need to be U.S. citizens for at least one month before the primary and residents of Pennsylvania and the election district in which you want to register and vote for at least 30 days.

Residents may apply in person at a county voter registration office; the state departments of public welfare or health; Pennsylvania Department of Transportation photo and driver's license centers; armed forces recruitment centers; county clerk of orphan's courts or marriage license centers; area agencies on aging; county mental health and intellectual disabilities offices; student disability services offices of the State System of Higher Education; offices of special education in high schools; and Americans with Disabilities Act-mandated complimentary paratransit providers.
